Stereospecificity - Rittaito Kuisei (English spelling) stereospecificity

Japanese: 立体特異性 - りったいとくいせい(英語表記)stereospecificity
Stereospecificity - Rittaito Kuisei (English spelling) stereospecificity
When a stereoisomeric reactant gives a stereoisomeric product, the phenomenon in which a specific stereoisomer gives a specific stereoisomer is called stereospecific, and such a process is called a stereospecific process. According to this definition, different stereoisomers of the reactants give different stereoisomers of the product. A typical example is the Walden inversion. The addition of bromine to an alkene is stereospecific. In other words, in the addition of bromine to the geometric isomers of 2-butene, the trans isomer stereospecifically gives meso-2,3-dibromobutane, and the cis isomer stereospecifically gives (±)-2,3-dibromobutane.

Japanese:
立体異性体をもつ反応物が立体異性体をもつ生成物を与える際,特定の立体異性体が特定の立体異性体を生じる現象を立体特異性,その種の過程を立体特異的過程という。この定義によると,反応物の別の立体異性体は生成物の別の立体異性体を与える。典型的な例はワルデン反転である。アルケンに対する臭素の付加は立体特異的である。すなわち2‐ブテンの幾何異性体への臭素の付加において,トランス体はメソ‐2,3‐ジブロモブタンを,シス体は(±)‐2,3‐ジブロモブタンをそれぞれ立体特異的に与える。
